Spanish Judge José de la Mata has issued an arrest warrant for Israeli Prime Minister Benjamin Netanyahu and seven other former and current government officials in relation to the 2010 Israeli attack on the Freedom Flotilla of civilian vessels carrying relief supplies to the Palestinian city of Gaza.

In May 2010, Israeli commandos stormed the Gaza Freedom Flotilla of seven ships carrying humanitarian aid and construction materials, along with 590 passengers. In the raid, nine of the aid activists, including eight Turkish citizens, were killed in the raid and a tenth died in hospital later.

A Sept. 2010 report by the United Nations High Commission on Refugees called the Israeli blockade illegal and said that Israel’s actions were “disproportionate,” had “betrayed an unacceptable level of brutality” and that there was evidence of “willful killing” on the party of the Israeli military.

In issuing the arrest warrants for Netanyahu and the other Israeli officials, Judge Mata said he would reopen the case in Spain’s Supreme Court should Netanyahu or any of the other named individuals set foot in Spain.
